Sisters Elisabetta and Francesca Grillo have agreed to speak exclusively to This Morning, for the first time since being acquitted of fraud charges made against them by Charles Saatchi and Nigella Lawson.

Accused of racking up over £685,000 of debt on the former couple's credit cards, the sisters claimed that they had been allowed to use the cards in exchange for staying quiet about Nigella's alleged daily drug abuse.

Phillip Schofield and Christine Bleakley will interview the sisters to hear what it was like to live with the famous TV chef, who was forced during the trial to admit to drug use.

"I feel sorry that we ended up in that situation, that she did admit to that," said Lisa. "But no, not guilty, because it was nothing to do with me, it's her life".

"I think maybe we won the case but definitely she had the most support from the public," added Francesca. "She is well loved and she will always be loved. I'm sure she will be fine. She's great at what she's doing and I wish her all the best."
